Specification of Letters Patent. Patented Jan, 1'1, f911, Application filed May 13, 1909. Serial No. 495,819. i

i To all whom it may concern:

' matter, and 'it has for its object to provide a novel Babbitt or bearing metal which shall be specially adapted for use as a lining for bearing boxes and for similar purposes.

When ordinary Babbitt metal is used constantly in the manufacture of bearings, the chi and turnings are usually gat ered, me ted and recast, but it has been observed that, under these circumstances, the new product is inferior to the original, by reason of the fact that a good deal of dirt enters into its composition. According to my present invention, I provide a composition comprising a large percenta" e of chippings and turnings of ordinary abbitt metal, the quality of which is equal or superior to Babbitt metal as usually made. A

I prefer to utilize the following ingredients in the proportions indicated: lead 83-1/3 parts, tin 81/3 parts, antimony -81/8 parts, vanadium, appzoximately 174-- part. The vanadium may added in any suitable form and may vary from 1/f)0% to 1/2%,and yet still produce the desired result. I prefer to add the vanadium in an alloy of copper containing about vanadlum.

I claim as my invention:

1. A composition of matter composed of a 'large percentage of a lead alloy and a very small percentage of vanadium.

2. A eomposltion of matter composed of a large percentage of lead, small percentages of tin and antimony and a very small percenta e of vanadium.

. 3. composition of matter composed of the following ingredients in the proportions indicated: lead 83-1/3%,.tin' 81/3%, antimony 8-1/8%, vanadium, approximately 4. A composition of matter composed of I JESSE L. JONES. Witnesses:
